HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 490,574, dated January24, 1893.

Application nga october 22,1892.

To all whom t may concern:

Be it known that I, VICTOR MATHIEU, of Inverness, in the county ofCitrus and State of Florida, have invented certain new and usefulImprovements in lIoisting Apparatus; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

Myinvention relates to an improvementin hoisting apparatus; and itconsists in the novel construction and arrangement of parts, all ofwhich will befully described hereinafter and more particularlydesignated in the claims at the end of this speciiication.

The object of my invention is to provide an improved hoisting apparatushaving a movable carriage which is adjustable on a track or way betweenthe vertical supports, and which is so arranged as to prevent anypossible entanglement of the several cables.

Referring to the accompanying drawings,- Figure l, is a side elevationof my improved hoisting apparatus. Fig. 2, is an end view of the same.Fig. 3, is a detached view of one of the combined rope supports andguides.

A and B designate the respective supports or towers which are arrangedat opposite sides of the point over which the hoist is to be operated.Securely fastened to these towers is the cable C constituting a trackover whichV moves the carriage D. The latter consists of a suitablenumber of cross bars to insure strength. Journaled in the upper portionof the carriage structure are the peripherally grooved wheels E whichsupport and transport the carriage on the way C. In the lower portion ofthe carriage are the wheels F and Gr over which the hoisting cabletravels presently to be described.

Projecting from the upper end of tower A are the bearings H and journaled across them is the shaft I to which are secured the sheaves Jand K. Similarly mounted on the tower B is the sheave L.

Arranged at a convenient point adjacent the base of the tower A is thespirally grooved drum M around which the rope N is wound three or moretimes. The shorter portion N of this rope is passed up over the sheave KSerial No. 449,663. (No model.)

and outward therefrom where it is secured to the end of the carriageadjacent the tower A, as shown. The other or greater portion N of therope N is extended over the sheave J, and from thence to the sheave L onthe tower B around which it passes back to the carriage to which it issecured at a point opposite the end of the portion N. By thisconstruction it will be seen that by revolving the drum M either one wayor the other the carriage may -be adjusted on the way C in a mostconvenient manner. No source of power is here shown for operating thedrum, but the same may be conveniently driven by an engine, as will bereadily understood.

Secured to and Wound upon a suitably operated drum O is the rope P whichpasses upward over a sheave Q, suitably journaled in the tower A.Continuing outward from this point the said rope extends outward overthe wheel F, then downward around the hoisting hook pulley R, and upwardtherefrom around the wheel G from which latter it depends, its end beingsecured to the frame of the pulley R, as shown. This rope P constitutesthe hoisting cable which may be operated from the drum O, so as to raiseor lower the hoisting pulley R Whenever it is desired to do so. Thelongitudinal adjustment of the carriage on the way C, enables theoperator to place the hoist at any desired point between the towers.

Supported and adapted to move on the way C are combined rope supportsandguides S having outwardly flaring arms T at their upper ends forguiding or confining the portion N of the carriage shifting rope N. Thesaid rope portion is prevented from sagging orbecoming entangled withthe hoisting rope P or Way C, when slack occurs therein. These devices-S are supported on the way C by the rollers U journaled between theirsides so that they move freely on the said way. In the lower ends of thedevices are the rollers V, and over them passes the ropeP on its way tothe carriage. Thus the said rope is supported in line with the Way C andprevented from sagging. The adjacent lower ends of the combined guidesand supports are connected by the chains YV so that in moving outwardover the way C they will be prevented from moving too far apart. Asshown in Fig. 3, the vertical sides of the above described ICOsupportingand guidingdevices may be formed of a single piece of metal bydoubling the same at its lower end.

The towers A, B, may be arranged any desired distance apart, so that thehoist maybe operated over considerable space.

The ends of the Way C are shown extending over and beyond the towers tosuitable anchorages, which though not shown will be readily understood.

Having thus fully described my invention what Iclaim as new and desireto secure by Letters Patent, is

l. In an apparatus of the class described, the combination of twotowers, a track or way supported thereby, a carriage on said way, a ropefor moving backward and forward the said carriage, guides supported onthe track or way having upwardly extending daring arms for guiding thesaid rope, and a hoisting rope supported by the carriage, substantiallyas shown and described.

2. In an apparatus of the class described, the combination of a suitablysupported track or way, a carriage thereon, a suitably operated rope foradjusting the carriage on the way, combined guiding and supportingdevices movable on the said way, upwardly eX-` tending aring arms at theupper ends of the devices for guiding the said rope, a hoisting ropeextending to the carriage, and rollers in the lower ends of the saidguiding and supporting devices over which the said last named ropepasses, for the purpose shown and described.

3. In an apparatus of the class described, the combination of a suitablysupported track or way, a carriage, a rope for adjusting the same, asuitably operated hoisting rope passing to the carriage, movable deviceson said way having forked upper ends for guiding the first named rope,the sides of each of the said devices being formed of continuous piecesof metal, rollers in the lower ends of the devices over which passes thesaid hoisting rope, and connecting chains between the said devices,substantially as shown and described.

In testimony whereof I affix my signature in presence of witnesses.

VICTOR MATHIEU.
